Title: Improvements in or relating to the electrolytic deposition of lead peroxide
IPC: C25B11/16
Filed: 1935-11-01
Abstract: 456,082. Electrolytic deposition of lead peroxide. KATO, Y., 1220, Togoshimachi, Ebara-ku, Tokio. Nov. 1, 1935, Nos. 30244 and 30245. Convention dates, Dec. 20, 1934 and April 4, 1935. [Class 41] A compact and adherent layer of lead peroxide is deposited on the concave surface of a base body connected as anode. In order that the base may be of sufficient strength to resist expansion forces called into play during deposition the product of its thickness in millimeters and the tensile strength of the material in kilograms per square millimeter should be greater than 1. Alternatively the base may be wound with wires or otherwise reinforced. In an example deposition is effected on the inside of a hollow cylindrical nickel or nickelplated anode of internal diameter 3 dcm. and thickness 0À25 dcm., with a carbon cathode disposed within the anode. The electrolyte consists of 18 kgms. of lead nitrate dissolved in 40 litres of water with the addition of 20 gms. of a hydrophile colloid such as gelatine or glue. A layer of peroxide 2 mm. in thickness may be deposited. The coated bases may be used as anodes in the electrolytic production of chlorine and hypochlorites from brine, and of perchlorates from chlorates. In an example a 40 per cent solution of sodium chlorate containing 1 per cent of sodium bichromate is electrolyzed at 20‹ C., with an anode having a lead peroxide layer and a cathode of iron. The sodium bichromate may be omitted if a chromium plated cathode is employed.

Title: Improvements relating to the extraction of nickel from oxidic ores
IPC: C22B23/02
Filed: 1960-09-12
Abstract: Finely-divided oxidic nickel-iron ores are first treated to reduce the nickel and a part of the iron and to simultaneously sulphidize the nickel, the reaction being carried out essentially by a mixture of reducing and sulphur-containing gases which may be produced inside or outside the reaction vessel.  The treated ore is then smelted to yield a matte from which nickel may be obtained by conventional means.  The gas mixture for the first stage may be obtained by controlled combustion of high-sulphur fuels possibly augmented by the addition of sulphurous gases from the nickel extraction stage. The matte is preferably first blown to slag off iron, the slag being returned to the matte smelting stage.  After iron removal cobalt may be removed by blowing the melt while retaining a sulphur content of at least 3%.  Nickel may then be obtained by the process disclosed in Specification 960,698.
